Ferritin
28 µg/L
Hi, I'm Elisa.
If you're trying to conceive and every result comes back "normal," single lab values and general advice can't tell you what is going on. I read your biology as one connected system and show you where to start.
A reference range shows where about 95% of a tested population falls. It was built to flag disease. It was never designed to tell you whether your body is in a good position to conceive, or whether the right tests were taken on the right day.

Examples, not a diagnosis. The lines are the ones described in the Journal, with their sources. Read the evidence behind it
Each has a studied effect on ovulation, egg quality or implantation. The free assessment shows which one is most likely leading yours.
You feel wired but exhausted. Your sleep is light, you wake between 2 and 4am, and your period flattens you. When stress goes on for months, it can switch off the signal that starts ovulation.
Your cycle runs long, short or just feels off. You were told your thyroid and hormones are normal, yet ovulation seems weak or late. Small shifts here look normal on paper and still change how your cycle behaves.
Energy crashes after meals, cravings you can't explain, weight that won't shift. You don't have a PCOS diagnosis, yet mild blood sugar problems can disrupt ovulation long before anything reads as abnormal.
Everything looks fine, but you're tired and sense your body is running on empty. The raw materials your eggs depend on can sit below the level that matters for fertility and still count as normal.

How it worksWhat women told me after taking the free assessment.
"After 14 months of trying with 'normal' test results, I finally understood where to focus instead of wondering what I was missing. For the first time, I felt like I had a real plan."
"I expected another generic fertility quiz. Instead, it connected symptoms I'd never linked before and showed me why I constantly felt depleted. It was the first time everything actually made sense."
"After hearing 'everything looks normal' for 18 months, this was the first thing that actually reflected how I felt. I finally stopped blaming myself and knew where to begin."
"I walked away with clear next steps instead of another list of things to try. The results felt incredibly personal, and surprisingly accurate."

I'm a functional fertility coach and certified nutritionist. I read the body as one connected system and turn what it is signalling into a decision you can act on, always alongside your medical care.
This work grew out of my own experience, and out of watching too many women hear that everything looked fine when it clearly didn't. I trained clinically in Southern California, built my practice with women across the US and moved back to Germany in 2025.

Yes, it was built for exactly that. I read your results with conception in mind, not only against the lab's "normal," so you can see where there is still room to improve.
No. It is an evidence-informed interpretation of your own signals, meant to be read alongside your provider and never instead of them. I don't diagnose disease, and I'm clear about where the evidence is settled and where it is still developing.
